This is stressful, relaxing, disconcerting, and somehow dizzily cheerful at the same time. I don't understand, but that weird portamento shit going on with the piano is making my ears wiggle.
As always, your creative approach to sound design makes me feel like a wee babe. I feel your pain with the writer's block.
The only thing I don't like is that LFO around 2:00. And the final section, whiile immensely groovy, feels a bit unfinished. The drums miight be clipping. I can't tell. I'd like some wonky FX on the hats, maybe some stereo play. But now I'm just nit-picking.
Great work! :)
